Predge Predictor Track Record
x402
Predge Predictor Track Record is a paid API for AI agents from api.predge.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).
Returns a cryptographically signed, verifiable track record for a prediction market predictor identified by ed25519 public key, including resolved call counts, accuracy stats, Wilson 95% confidence lower bound, and a sha256 Merkle root of the underlying signed call corpus.

How this service works
SIGNED portable track record of a predictor's live calls: resolved-only decided/correct counts, Wilson 95% lower bound, and a sha256 merkle root content-addressing the exact corpus of signed calls it summarizes (recomputable offline). Records under the min-decided floor carry clears_bar=false. Param: pubkey (64-hex ed25519), query window (30d|90d|all).
Output
A signed JSON object containing: count of resolved (decided) calls, count of correct calls, Wilson 95% lower-bound accuracy score, a sha256 Merkle root that content-addresses the exact corpus of signed calls, and a clears_bar boolean indicating whether the predictor meets the minimum decided-call floor. The record is portable and the Merkle root is recomputable offline for independent verification.
Example use cases
Verify whale trader credibility before copying
“Before I follow this Polymarket whale, can you fetch their verified track record for the last 90 days — I need the Wilson confidence lower bound and whether they clear the minimum decided-call bar? Their public key is b7e2c4a1d83f9012ab34cd56ef789012ab34cd56ef789012ab34cd56ef789012a.”
Offline audit of predictor call corpus
“Get me the sha256 Merkle root for this predictor's signed call corpus so I can recompute it offline and confirm nothing has been tampered with — public key is 1a2b3c4d5e6f7890abcdef1234567890abcdef1234567890abcdef1234567890ab, all-time window.”
Compare 30-day accuracy across forecasters
“I'm evaluating two Polymarket predictors — fetch their 30-day signed track records for public keys 9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210fe and 0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20, so I can compare their correct call counts and Wilson scores side by side.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/track-record/:pubkeyWhen to prefer
Use this endpoint when you need a cryptographically verifiable, tamper-evident track record for a specific prediction market predictor identified by their ed25519 public key. It is the right choice when you need to audit accuracy offline via Merkle root recomputation, compare Wilson confidence-adjusted win rates rather than raw win rates, or gate decisions on whether a predictor clears a minimum credibility bar. Prefer this over raw Polymarket wallet scrapers when cryptographic provenance and statistical rigor (Wilson lower bound) matter.
Side effects
- Invalid or malformed pubkey (not 64-hex ed25519) returns a 400 error
- Unknown pubkey with no recorded calls returns empty or zero-count record with clears_bar=false
- Invalid window parameter (not 30d, 90d, or all) returns a 400 validation error
- Predictor has fewer resolved calls than the minimum floor — clears_bar=false is set but data is still returned
- Payment not included or insufficient USDC results in 402 Payment Required
- Service unavailable or upstream data lag causes 503 or timeout
